FOLDING AND CONVERTIBLE C OT 0 R BED.

SPECIFICATION forming part of Letters Patent No. 758,211, dated April 261904.

Application filed my 14, 1902. Serial No. 115,49o. (No model.)

To aZZ whom it may concern:

Be it known that I, JOSHUA W. J ONES, of Harrisburg, in the county ofDauphin, State of Pennsylvania, have invented certain new andusefulImprovements in-Folding and Con vertible Cots or Beds; and Ihereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, forming apart of this specification, and to the letters of reference markedthereon.

This invention relates to improvements in devices ordinarily adapted toform a cot or,

single bed and to be readily folded into small compass to facilitatestorage or transportation; and the invention has for its object toprovide a structure of this character havingacapacity for beingconverted into any one of a large a side elevation of a convertible cotembody ing the present improvements. Fig. 2 is a longitudinal sectionthrough the same with the stuffed mattress removed and some of theadjustments indicated in dottedli'nesi. Fig. 3' is an end elevation.Fig. 4 is a detail per-- spective view of the side pieceor convertibletable attachment. Fig. 5. is a detail view of one end of the stuffedmattress and of one end of the single mattressf Fig. 6 is a sectionalview through one side of the head-section, the view being taken in theplane of the joints and bearings. Fig. v7 is a bottom-plan view. Likeletters of reference in the several figures indicate the same parts. a

' As shown in Fig. 1 of the accompanying drawings, itwill be seen thatthe device takes the form of a cot or couch, and the body portionthereof is preferably formed by two frames, one constituting the mainframe or body-section proper and the other the headsection. Thebodyportion of the frameis indicated by the letter A, and as showninFig.

are extended past the pivots B and are provided with notches c for thereception of one or another of a series of projections c on the legs C,which latter are pivoted at their up-' per ends to the sides of the mainframe. By

this construction the inclination of the head section may be varied atwill and when adjusted to suit the convenience of the'user may be firmlyclampedin position.

At the foot ofthe main frame there is provided a frame D, pivoted to themain frame by pivots 65 the upper'portion of which is in the form of across-bar d, adapted to receive one end of the mattress, as willpresently ap- I pear, while the lower portions of said frame constitutebraces adapted to cooperate with legs D, pivoted at their upper ends tothe main frame and having projections d, with'which operate. l

The legs at both ends of the cot are provided with projections whichextend inwardly, such projections being indicated by the letter E, and

recesses or slots in the ends of the frame C comay be formed either byextensions of the projections with which the braces cooperate or asindependent projections rigid with the legs. Such projections areadapted to cooperate with stretcher-arms F, pivotally connected at' oneend with the frame of the cot and adapted to swing, as indicated in fulland dotted lines in the drawings, so as to project to form stretcherarmsor so as to extend down vertically and by cooperation with theprojections E form an inconspicuous position where they will be out ofsight and will not interfere with th other adjustments of the structure.

The primary mattress for'the cot is prefer' ably a tension-mattress andmay be formed of canvas or woven Wire or other material. One end isadapted to be secured to the cross-bar of the foot-frame, while theopposite end is adapted to be secured to the roller in the headsections.The connection between the primary mattress, which is lettered G in theaccompanying drawings, and its supports is preferably formed by metallichooks G, securely fastened to the ends of the mattress and adapted theone to hook over the cross-'bar of the foot-frame and the other to hookinto a slot in the roller of the head-section. Obviously the mattressmay be of greater length than is ordinarily required should it betensioned directly between the roller and cross-bar, and thus a varietyof adjustments'are provided for. For instance, said mattress may bepassed under the intermediate cross-bar H, hung from the pivots B of thehead-section, so as to form a couch, or it may be swung from the rollerdirectly to the cross-bar of the foot-frame to give a hammock effect,and the intermediate cross-bar under such circumstances may be swungdown out of the way. If it is desired that one end of the hammock shouldbe higher than the opposite end, the head-section may be inclined togive the desired elevation, and if a still further elevation is desireda supplementary orshelf section I may be brought into play and themattress passed overthe top of the same and down to the roller, asbefore. This supplementary or shelf 'sectionI is preferably providedwith a flat surface upon which articles may be placed in convenientposition to be reached by the user of the couch, and it is furthermoreprovided with extensions 6, em-

' bracing the pivots or adjusting-screws of the In some situations it isconvenient for use as a support for a canopy or mosquito-netting, asindicated in dotted lines in Fig. l, and to elevate suchmosquito-netting above the foot of the cot the stretcher-arms may beswung upwardly for that purpose.

Obviously projectionssuch, for instance, as indicated at e"may beprovided on the head-section and corresponding recesses in theshelf-section for locking the same rigidly in adjusted position when theroller-screws are set up. Projections K and corresponding shoulders Kare also provided on the stretcherarms and main frame for limiting themovement of 'said arms in one direction, whereby they may be maintainedrigidly in their horizontal position with sufficient strength to supportthe weight of the occupant of the couch when the latter is used as astretch-eror carrying-bed.

An attachment adapted to form a side board for the cot or couch is alsopreferably provided, such attachment, however, being well adapted forother uses, as will presently appear. This attachment consists of aboard L, having at one end a pivoted clamp L, ad-

of the cot, thereby forming an effectual side board or back should thecouch be used as a seat instead of a bed. The board L being adjustable,however, in the manner stated may be readily swung up to form a table orreading-board, or it may be provided with pivoted sections L*, which mayform legs if the table be located at one side of the cot, or it may belocated in such position as to form an extension-table when the cotitself is elevated for use as a mess-table, the latter being one of themost easily-made adjustments and one of the .most useful in ordinarycamp usage.

In connection with the primary mattress before referred to a stuffedmattress N is also preferably provided for use, particularly where thestructure is to be converted into a couch or divan, under whichcircumstances the stuifed mattress is laid over the primary mattress andits ends are connected with the cross-bar of the foot-frame and rollerof the head-frame by hooks M, which latter are made of sufficient sizeto fit over or nest with the hooks on the primary mattress, whereby bothmattresses may be tensioned simultaneously, and at the same time thestrains incident to usage will be taken up by the primary mattress andwithout unduly stretching the stuffed mattress.

With the structure illustrated and described many adjustments may beeffected not hereinbefore specifically referred to; nor is it thoughtnecessary or desirable to mention all of the possibilities of thestructure, especially as in use such adjustments will naturally occur tothose familiar with the cot; but attention is called to the fact thatnot only may the headsection be turned down parallel with thebodysection, so as to form a long cot, but by the use of thestretcher-arms as legs the structure so formed may be elevated toconstitute a long and very effective table, which may be used for messor surgical purposes at will, and by the releasing of the legs at thefoot end of the cot it may be made into an inclined couch or chair of acharacter common for invalid use bination with the rectangular mainframe, the

head-section pivotally connected with one end thereof, and extended toform leg-braces and legs pivotally connected with the main frame, of afoot-frame pivotally connected with the main frame and having across-bar and extensions forming leg-braces and a suspended mattresssupported at one end at the foot of the main frame and at the oppositeend at the upper portion of the head-section; substantially asdescribed.

2. In a structure such as described, the combination with therectangular main frame, of the legs pivotally connected to said frame,the head-section pivotally connected to the main frame and having anextension pivotally and adjustably connected with the legs, whereby thehead-section may be adjusted in position, the foot-frame pivotallyconnected to the main frame and its cooperating legs, a mattressconnected at one end with the foot-frame, and adjusting mechanism forthe mattress carried by the head-section to which the opposite end ofthe mattress is connected, whereby the mattress may be tensioned withthe head-section at different inclinations; substantially as described.

3. In a structure such as described, the combination with the main framehaving legs pivotally connected therewith, ahead-section and afoot-frame pivotally connected with the said main frame and cooperatingwith the legs to position the same for supporting the mainframe,stretcher-arms pivotally connected with the main frame and adaptedto project beyond the same horizontally, cooperating projections andrecesses on the stretcher-arms and legs whereby said arms may serve asextensionlegs and a mattress carried by the main frame and head-section;substantially as described.

4. In a structure of the character described, the combination with themain frame, legs pivotally connected therewith and head-section andfoot-frame for positioning said legs, of the stretcher-arms pivotallyconnected with the inner sides of the main frame and having a shoulderat one end and adapted to swing to form horizontal extensions beyond themain frame and stops or projections on the main frame with which theshoulders on the same cooperate for holdingsaid arms against swingingupwardly beyond a horizontal position, whereby they may serve as handlesfor carrying the structure and its occupant; substantially as described.

5. In a structure such as described the combination with the main frame,adjustable legs for supporting the same, the head-section pivotallyconnected to the main frame and having an extension pivotally andadjustably connected with the legs, the foot-frame pivotally connectedto the main frame and its cooperating legs, a mattress connected at oneend with the foot-frame, an adjusting mechanism for the mattress carriedby the head-sectionto justably connected with one end of said main.

frame, of a roller journaled in said head-section, clamping-screws forclamping said roller in its adjusted position, a suspension-mattress andmeans for removably connecting one end of said mattress with the footend of the main frame and the opposite end of said mattress with saidroller; substantially as described.

7. In a cot structure such as described, the combination with the mainframe, legs adj ustably connectedtherewith and a head-section adjustablyconnected with one end of said main frame, of a removablesuspension-mattress having hooks secured thereto at opposite ends andadapted to engage respectively a crossbar at the foot end of the mainframe and a tensioning device at the upper end of the headsection;substantially as described.
